Randomly assigns a starting point for the EM algorithm
This function should be invisible to most users, and is part of our the fitting routine using the EM algorithm. Our maximum likelihood procedure uses an iterative algorithm called Expectation-Maximization. This requires a starting point, chosen at random. EM.starting point randomly assigns this starting point.
EM.starting.point(d, trait = "binary")
The dataframe that needs to be initialized
Can be either “binary” or ”eQTL”
Returns the input data frame with reasonable random starting values.
